About this app

Duo Mobile works with Duo Security's two-factor authentication service to make logins more secure. The application generates passcodes for login and can receive push notifications for easy, one-tap authentication.

Additionally, you can use Duo Mobile to manage two-factor authentication for other application and web services that make use of passcodes.

Duo Mobile also has a companion app for Wear OS, Duo Wear, making secure authentication even more convenient on your smartwatch.

Note: For Duo accounts, Duo Mobile needs to be activated and linked to your account before it will work. You will receive an activation link as part of Duo's enrollment process. You may add third-party accounts at any time.

Additionally, we will request access to use your camera for the sole purpose of scanning QR codes when activating accounts. Accounts can be activated by other methods if you choose not to do so.

Ratings and reviews

I don't want to be forced to back up my entire phone to the cloud in order to be able to recover my duo accounts if my phone breaks (ie to set up a new phone without access to the old one). Let me have a password-protected backup for just duo! For me, this is a deal-breaker. I'm going to have to find another app. Otherwise the app is fine.

The app works fine but I can't get a feature fix that used to work. you used to be able to click approve from the notification that popped up when you signed in. now it gives an error message that you do not have. a mobile or Wi-Fi connection. when you open up the app, you can approve. please fix this bug so that you can approve a login from the notification that pops up instead of having to go into the app.

Doesn't always send push notifications, so I have to open the app. Other than that, great! Works well for authentication, and they recently added the ability to automatically transfer accounts to a new phone, which happened immediately and seamlessly for me :)
